This new 1,560 square foot, three bedroom, two bath residence replaces a Paradise, CA home destroyed in the 2018 Camp Fire. The owners wanted an attractive and modest house to live in while they built their dream home on an adjacent lot. The house will later be used as rental income and provide much needed housing in Paradise.
The back of the house faces west towards an excellent view of a stand of oaks that survived the fire. The large rear porch roof provides protection from unwanted glare and the setting summer sun, so the house does not overheat in the summer. The porch also extends the living space and provides excellent year round indoor/outdoor living. It is open framed with rafters so there is an expansive view to the forest and ample diffused daylight throughout the year. It also protects the home from prevailing weather patterns.
The open floor plan provides an outstanding space for entertaining guests with large windows bringing in the outdoors.
Even though the house is built on a sloped lot it is fully barrier free and employs universal design principles throughout including a curbless shower in the Primary Bath.
Several energy efficient materials and methods were used while staying within a modest construction budget. The roof uses a 12” energy heel to allow a consistent insulation blanket in the attic and blown-in blanket (BIB) insulation was used in the walls to provide an R-23 wall assembly, much better than code requirement and better than standard construction. A cool roof, foil backed roof sheathing, heat pump HVAC system, heat pump water heater, and a whole house fan round out the energy efficiency measures of this house.

Nestled in the lush landscape, a modern reinterpretation of a once-fallen barn now features a charming guest cottage with stylish details and contemporary amenities. Situated along a narrow lot in Germantown, New York, the cottage completes a cluster of existing buildings, forming an intimate courtyard on one side. Steel effect folding patio doors fully open the living areas to the expansive fields and the Catskill Mountains beyond.
The homeowners, a young family with parents living abroad, envisioned a cozy yet modern ADU for extended stays. Designed by Lauren Cawse, AIA, architect and partner at The Art of Building, the year-round retreat draws inspiration from traditional local barns while embracing a seamless indoor-outdoor connection.
Captivating Guest Cottage Design Enhances the Senses with Steel Effect Folding Patio Doors
The modern ADU design started with the site itself. Positioned between residential and commercial neighbors, the elongated property required a careful balance of privacy and openness. Architect Lauren Cawse approached the layout by redefining the existing house and garage as the east and west sides of an outdoor room, with the new cottage forming its southern boundary. This arrangement created a clear courtyard near the main residence while directing the 800-square-foot guest house toward the open meadow and the distant Catskill Mountains.
“The unique character of the site and its history inspired the architectural direction,” says Cawse. “The intent was to create a secondary structure in the compound in clear contrast to the modern farmhouse style of the house and garage.”
A Barn-Inspired Exterior Adds Visual Flair
The exterior envelope evokes a traditional barn with a simple gable shape, weathered wood siding, cedar shingles, and a foundation veneer made of local fieldstone. A large sliding barn door adds a complementary feature to the courtyard-facing side, creating a dynamic opening that maintains uninterrupted views through the cottage to the meadow beyond.
Steel effect folding patio doors surrounding the structure add a modern touch of transparency, and simulated divided lites allow the contemporary glass wall systems to harmonize with the traditional elements of the modern ADU design.
“The goal was to fully open the living areas to the outdoors, framing views to the meadows and mountains,” says Cawse. “The positioning of the NanaWall systems frames the views and, when open, dissolves the boundary between inside and out.”
Interior Design That Mirrors Nature’s Tranquility
Inside, the design program features a simple layout with one bedroom, a full bath, a kitchenette, and a living area with a wood-burning stove. The interior, a collaboration between The Art of Building and the homeowners, is defined by an understated palette and tactile materials that reflect the natural setting. Color is introduced through the framed glass views on all sides of the structure. Reclaimed timber collar ties span the ceiling overhead, while stone surfaces and naturally patinated metal accents add quiet texture throughout.
Custom hand-painted Delft tiles along the kitchen backsplash add personal detail, and terra cotta flooring in the bathroom brings warmth and old-world charm. Soaring ceilings and abundant daylight create a peaceful play of light and shadow, shifting subtly with the seasons and emphasizing the cottage’s connection to the natural landscape outside.
Sleek Steel Effect Folding Patio Doors Elevate the Modern ADU Design Aesthetic
Three customized steel effect folding patio doors define the living space, each aligned to respond to a different edge of the site. The largest, spanning nearly 20 feet wide and just under eight feet tall, opens directly onto the stone patio, allowing the main gathering area to extend fully into the landscape. Along the side of the living room, a smaller 10-foot-wide system introduces more light and ventilation, nearly creating an open corner condition if not for the structural post that supports the façade and roofline.
At the rear, a fourth ten-foot-wide system features a French door swing panel configuration that opens toward the courtyard, strengthening the design connection to the main residence. All steel effect folding patio doors were specified with a low-maintenance, water-rated Performance Sill to safeguard against inclement weather while providing a seamless, barrier-free transition to the outdoor patio.
Unique Customizations for Visual Appeal and a Steel Effect
Each folding patio door system is configured to open outward, maximizing usable floor space in the compact interior and allowing furniture placement to remain uninterrupted. By stacking outward, the steel effect folding patio doors, specified in a SE Classic Bronze powder coat, ensure every inch of the cottage is optimized. Simulated divided lites create a consistent rhythm across windows and doors, maintaining alignment with the traditional barn-inspired exterior.
In the bedroom, a three-panel, 10-foot-wide system mirrors these customizations, matching the steel effect divided-lite pattern and outward-opening configuration, extending the indoor-outdoor connection while preserving visual continuity throughout the ADU.
“The divided lites were crucial to the architectural vision, and while budget prohibited a steel and glass system, NanaWall Systems’ thin frames provide the open and airy feeling we hoped to attain,” says Cawse. “Simulated divided lites transition the thoroughly modern element of the glass walls to remain in harmony with the otherwise traditional palette.”
Matching Windows and Doors: Create a Cohesive Design Program
Alongside the larger openings in the living areas and bedroom, a smaller 3-foot-tall NanaWall tilt turn window was added to the bathroom. This window-sized NanaWall system perfectly matches the divided lite panels and sleek frames of the steel effect folding patio doors, creating a cohesive modern ADU design throughout. The compact opening provides ventilation and natural light, enhancing the spa-like atmosphere along with natural stone flooring. The matching glass lines and sleek profiles of the NanaWall Generation 4 comprehensive product line further unify visual consistency, allowing each system to fit into the architectural style seamlessly.
“This project had three bifold glass walls, a pair of double French doors with sidelites, and a single tilt turn window,” says architect Lauren Cawse. “Being able to work with a single manufacturer provided aesthetic cohesiveness and simplified coordination.”
Sustainability Where It Matters Most
New York weather can vary from hot 85-degree summers to cold 26-degree winters. Creating an efficient living space was a primary goal. To achieve this, the design included Timber HP-insulated walls and floors with a heat pump system for effective heating and cooling. Additionally, the steel effect folding patio doors and windows were specified with double-glazed panels to ensure a tight building envelope.
Indoor-Outdoor Living Spaces for Relaxing and Entertaining
In-house landscape designer Liz Pulver worked closely with the team to conceive open-air spaces that enhanced the connection between inside and outside. To the south end of the lot, the landscape transitions into an “enhanced meadow,” allowing the cottage to feel embedded within the surrounding fields rather than set apart from them. A circular pool was designed to mimic a natural pond with a modest footprint. Around it, a minimalist fence and sunken stone ha-ha wall offer discreet safety for young children.
Limited space due to existing infrastructure and zoning setbacks left only a small footprint for the swimming pool, prompting the designer to propose a circular form that maximized the usable swimming area. “We felt that the perfect way to integrate a pool into the property and to honor the landscape would be to treat the pool as a piece of art itself,” says Pulver. “The result is a beautiful round pool that serves as both a functional retreat and a sculptural moment.”
Final Thoughts: A Barn-Inspired Design for Contemporary Living
This modern ADU design skillfully combines modern features with the enduring charm of traditional barns. The outcome is a welcoming living space that stands out amid a stunning landscape. Natural materials that mimic the beauty of the outdoors, expansive steel effect folding patio doors that fill the space with fresh air and natural light, and a restrained interior design work together to create an inviting retreat for everyday living, throughout the seasons.
“When entering the site, the cottage feels as though it was always there,” says Cawse. “It achieves its two opposing goals by creating a feeling of intimacy and enclosure near the house while also functioning as a threshold to the expansive fields and views beyond.”

This new 1,560 square foot, three bedroom, two bath residence replaces a Paradise, CA home destroyed in the 2018 Camp Fire. The owners wanted an attractive and modest house to live in while they built their dream home on an adjacent lot. The house will later be used as rental income and provide much needed housing in Paradise.
The back of the house faces west towards an excellent view of a stand of oaks that survived the fire. The large rear porch roof provides protection from unwanted glare and the setting summer sun, so the house does not overheat in the summer. The porch also extends the living space and provides excellent year round indoor/outdoor living. It is open framed with rafters so there is an expansive view to the forest and ample diffused daylight throughout the year. It also protects the home from prevailing weather patterns.
The open floor plan provides an outstanding space for entertaining guests with large windows bringing in the outdoors.
Even though the house is built on a sloped lot it is fully barrier free and employs universal design principles throughout including a curbless shower in the Primary Bath.
Several energy efficient materials and methods were used while staying within a modest construction budget. The roof uses a 12” energy heel to allow a consistent insulation blanket in the attic and blown-in blanket (BIB) insulation was used in the walls to provide an R-23 wall assembly, much better than code requirement and better than standard construction. A cool roof, foil backed roof sheathing, heat pump HVAC system, heat pump water heater, and a whole house fan round out the energy efficiency measures of this house.

A cool roof, foil backed roof sheathing, heat pump HVAC system, heat pump water heater, and a whole house fan round out the energy efficiency measures of this house.

This new 1,560 square foot, three bedroom, two bath residence replaces a Paradise, CA home destroyed in the 2018 Camp Fire. The owners wanted an attractive and modest house to live in while they built their dream home on an adjacent lot. The house will later be used as rental income and provide much needed housing in Paradise.
The back of the house faces west towards an excellent view of a stand of oaks that survived the fire. The large rear porch roof provides protection from unwanted glare and the setting summer sun, so the house does not overheat in the summer. The porch also extends the living space and provides excellent year round indoor/outdoor living. It is open framed with rafters so there is an expansive view to the forest and ample diffused daylight throughout the year. It also protects the home from prevailing weather patterns.
The open floor plan provides an outstanding space for entertaining guests with large windows bringing in the outdoors.
Even though the house is built on a sloped lot it is fully barrier free and employs universal design principles throughout including a curbless shower in the Primary Bath.

Our pioneer project, Casita de Tierra in San Juan del Sur, Nicaragua, showcases the natural building techniques of a rubble trench foundation, earthbag construction, natural plasters, earthen floors, and a composting toilet.
Our earthbag wall system consists of locally available, cost-efficient, polypropylene bags that are filled with a formula of clay and aggregate unearthed from our building site. The bags are stacked like bricks in running bonds, which are strengthened by courses of barbed wire laid between each row, and tamped into place. The walls are then plastered with a mix composed of clay, sand, soil and straw, and are followed by gypsum and lime renders to create attractive walls.
The casita exhibits a load-bearing wall system demonstrating that thick earthen walls, with no rebar or cement, can support a roofing structure. We, also, installed earthen floors, created an indoor dry-composting toilet system, utilized local woods for the furniture, routed all grey water to the outdoor garden, and maximized air flow by including cross-ventilating screened windows below the natural palm frond and cane roof.
Casita de Tierra exemplifies an economically efficient, structurally sound, aesthetically pleasing, environmentally kind, and socially responsible home.

Green Home Systems recently completed a successful solar project in Bloomsburg, PA for Eric M. The project was completed in a few months and consisted of 5.04 kW of solar panels installed on the flat roof of Eric’s home.
Eric chose Green Home Systems for their competitive pricing and wide selection of solar panels. He was also impressed with their warranty and customer service. After researching online, Eric decided to go solar to reduce his utility bill, increase the value of his home, and take advantage of the easy payment terms offered by Green Home Systems.
The installation process began with an inspection of the roof to ensure it was suitable for mounting the solar panels. The inspections revealed that some minor repairs were needed before installation could begin. Green Home Systems team quickly repaired any damage to the roof and got to work installing the panels.
Once the installation was complete, Eric quickly noticed a reduction in his monthly utility bills as well as an increase in the value of his home due to having clean energy sources available. He also was very pleased with how quickly and efficiently Green Home Systems completed the project.
The team at Green Home Systems is dedicated to providing customers with top-notch service and quality products at competitive prices. We strive to make your transition from traditional energy sources to renewable energy sources as smooth as possible by providing support throughout every step of the process.
